Europe's Coldest Cities in Summer. Europe's northernmost city has the continent's coolest summers. No other major city stays anywhere as tepid as ReykjavÃ­k, Iceland, where maximum temperatures average a meagre 12.7 degrees Celsius (54.8 degrees Fahrenheit). That's over five degrees Celsius (10 Â°F) lower than the next coldest city, Leeds.
During summer, the south of Europe can be very hot, while not so hot in the northern parts. The west of Europe is near the Atlantic, so it can get a lot of rain, even in summer, while other parts are a lot drier. There are a lot of Atlantic storms in winter that hit the west of Europe.
